Abstract
Macroscopic equations of adsorbed atom monolayer dynamics on a deformable crystal are derived. It is shown that a heavy decelerating adsorbed layer can induce two surface waves of the Rayleigh polarization. The higher-frequency one of them has the terminal point in the region of low wave numbers and changes into a pseudosurface longitudinal wave. In the case of a weakly bonded adsorbed monolayer the conditions for the appearance of weakly attenuating resonance modes are found. The situation is analysed for the case that the dispersion laws of the slow surface wave in the crystal with the adsorbed layer have the form ω∼k 1 2 typical for two-dimensional plasmons.
